walk on my knees

I can see my mother down on her knees scrubbing the kitchen floor.

Wow.

Now we have a Swiffer Generation. Zip in a disposable dry sheet for dusting, wet one for mopping, this done while standing erect with very little effort (and very little effect on the deep, down dirt, I might add).

Still, I remember the first time I washed up the kitchen floor - probably in my mid-teens - and thinking how arduous it was, and railing at the first person who tracked in dirt, my mother's age-old comment springing immediately to my lips -  'just look what you did to my nice clean floor!"

A little knee music goes a long way to understanding.
